The SupervisionMechanicsType provides Variables used for monitoring the Pump mechanics. It is illustrated in Figure 13 and formally defined in Table 31. For the generation of events, the SupervisionMechanicsType has references to the four Namur NE 107 statuses defined in OPC 10000-100. The InputNode Property of the Alarm shall contain the NodeId of the Component.
